MECHANISM FOR PRODUCING AN OSGILLATING MOVEMENTTO A SHAFT.

Specification of Letters Patent. PatentedAug. 31, 1915.

Application filed October 7, 1914. Serial No. 865,426.

To (ZZZ whom it may concern: i

a citizen of the United States, residing at Appleton, in the-county of Outagamie and State of Wisconsin, have invented a new and useful Mechanism for Producing an Oscillating Movement to a Shaft, of which the following is a specification.

My invention-is designed for operating washing machines in which the operating shaft of the mechanism which loosens the dirt and relievesthe clothes of the dirt, has

an oscillating movement, and the particular machine to which l have applied it having been patented by George M. Millar, June 6,.

1893, No. 499,136. It is adapted to be applied to any device in whicha slowv oscillat-.

ing movement'is required. v

'lhe invention is shown in the accompanying drawing in which,

Figure 1 is an end elevation of a washing machine having my improvement applied to it, with the washing machine shaft at one extreme limit ofits oscillation. Fig. 2 is a similar view of the Washing machine with its shaft at the other limit of its oscillation. Fig. 3 is a side elevation of the washing machine with my improvement applied to it,

body of clothes is between the squeezing plates of the machine than the space for the clothes is designed for, it will by reason of the resiliency of part of its mechanism, allow the revolutions of the revolving shafts of the mechanism without perceptibly interfering with the regularity of their revolutions or the power by which they are driven.

The device is adapted to be applied and is shown as applied to both hand and power operated machines, an electric motor and the necessary gearing being shown for reducing the speed to the desired rate for application in the most effective manner.

1, indicates a washing machine tub or inclosure; 2, its legs; 3, a lid hinged upon its top; 2, a girt between the legs; 4, its oscillatory shaft; 5, crank arms, one at each end naled in boxes 13 of the shaft; 6, a bracket secured to the legs Be it known that I, GILBERT W. .BUTTLES,

at one end of the inclosure by means of screws '7 mounted upon a pin 8, in said bracket is a wheel or pulley.

It should be observed that belt pulleys are shown in these drawings, but onaccount of the slow speed at which all of the shafts eX- cepting that of the electric motor and its connecting counter shaft are driven, sprocket.

anarm 10, having a pin 11, upon which a small roller 12, is loosely mounted. A. frame is mounted to oscillate upon the shaft 13 and is secured thereto, said shaft beingjour- The frame consists of a main bar 14, side pieces 15, secured to the piece 14: with screws 16, and a bar 17, is suspended from the pinlS and can swinga limited distance between the pieces 15, it having an arm 19, at right angles with it. The arm is provided with a right angled bend 20 at its free end, from whichbend a rod 21 extends to the bar 14. Mounted upon the rod 21,- is a spring 22, and it may also have a spring 22 y The spring here shown is represented as a rubber one, but a coiled wire one may be used if desired. Secured to the piece 17 with bolts 23, is a curved bar 24:, between which and the bar :17, the roller 12, is arranged to revolve as the frame is oscillated upon its shaft 13. At the lower end of the bar 14, an arm25, extends outward below the spring 22, from which a connecting rod 26 extends to the crank arm 5 upon the side of the machine having the frame just de scribed. Upon the opposite side of the ma chine an arm 27, similar to the arm 5, is secured to the shaft 13, and is connected by the rod 26 to the crank arm 5 upon that side.

In Fig. 4, the main bar 14, is extended upward and is provided with a handle 28, by

means of which the washing machine may In the drawings a motor 29, is shown,

which is supportedv upon the board 29*. It is provided with a pulley 30, from which a belt 31, is run to and around the large pulley 32 upon the shaft 33. From a small 20. p p I ,arranged to engageacompanion gear upon 'avertically arranged shaft 4 8, for operating p ne iiei, u fon the sha ft 33, a Belt runs c to "and around a pulley 36, upon the shaft 37, which is j ournaledin boxes 37 A small pulley 38 upon the shaft 37, carries, a belt 89, which runs to and around the pulley 9 upon the pin-8, of the bracket 6. The revolutions of the pulley 9, acts to swing the frame and through theconnecting, rods 26-,

tooscillate the shaft 4' of the machine. The shaft V3? is provided with spline 410,-and clutchi member 4:15, the pulley 36 having-integral withit the corresponding clutch member 42. A clutch operating: lever 43, is mounted upon a b'raclret tt, secured to a leg of. the machineand isfp rovid'ed with a plate 4C5, secured to another leg, said plate having.

a notchgtipinto which the lever is to be dropped for hold-ing the clutch members in engagement. the left end of the shaft 3 7, a 'beveled gear 4:7 is secured whichis a'wringer, not shown, which may besecured- :Copies of thfstpatent may he obtained f0 upon the top: of the machine iincl osure- With-the several shafts and p'u lleys shown, the speed ofthe motor canbe reduced to such a slowmovement as will best effect thewa'shingoperation. It-will be seen that by means of the springs'22 and 22 acting upon "the bar 17", that an oscillating movement 'canivbe given to the} shaft tof the ma chine that is notjpositi ve in its: terminals,

wheel'9 that a longer movementis made of the roller 12 in a partof the travel thereof than 'in the other part, which alternating long and short movements is just What the washing mechanism demands for effective work.

Having described my invention, what I claim and desire to secure by Letters Patent, 1s,

A; mechanism for imparting an oscillating movement to a shaft having a crank by which it may be revolved in which aspring acts: in limiting the terminals of its oscillations, consisting of a main bar having its point of'oscilzlation near one end thereof, a second: bar arranged parallel with and spaced from said main bar and pivotally connected with an arm thereof extending from its end opposite its pivotal end, an arm extending at right angles from the free end? of said second bar having an angular termination, a spring arranged between the outer enol of said angular terminal and the mainbar, a third bar arranged outside of parallel with said second named bar and spaced therefrom, in combination with adriven wheel mounted for revolution upon a 'suitable support and having an arm extending radially therefrom, a roller mounted for revolution upon the outer portion of said wheel arm between the second and third .named bars, an arm extending at right angles from the pivotal end of the main bar, and a connecting rod extending from the outer endof said main bar arm to a crank arm upon the aforesaid shaft to be oscillated.
